Invisible disabilities, also known as Non-Visible Disabilities (NVD), affect approximately 10 million people in France, accounting for 80% of individuals with disabilities. Despite their prevalence, these conditions—ranging from mental health disorders and chronic illnesses to neurodevelopmental and psychological conditions—are often unrecognized, leading to stigma, misunderstanding, and exclusion. This lack of recognition can create barriers to accessing support, accommodations, and equal participation in social, educational, and professional settings. This article explores the impact of invisible disabilities, shares personal testimonies, and discusses the crucial role of health professionals in supporting those affected by these hidden challenges.
